Speed of a black hole
WebMay 12, 2024 · A black hole is a location in space with a gravitational pull so strong that nothing, not even light, can escape it. A black hole’s outer edge, called its event horizon, defines the spherical boundary where the velocity needed to escape exceeds the speed of light. Matter and radiation fall in, but they can’t get out. WebNov 23, 2024 · HOST PADI BOYD: About 26,000 light years from Earth, the equivalent of 150 quadrillion miles, is the Milky Way’s supermassive black hole called Sagittarius A*. It’s called that because it is located in the constellation Sagittarius. HOST PADI BOYD: And you might be surprised to know that it wasn’t discovered until 1974.

It is a property due to curvature of spacetime because of the presence of a massive object. … WebIt is possible to measure the mass of a black hole from the speed of other objects. If we measure the speed of a star orbiting a black hole and the distance of its orbiting radius we can tell its mass. For example we would first locate a star that is traveling at 100 km/s and has an orbiting radius of 150 megameters so we could find the black ...
